Just updated my 3.4u wii to 4.0u and then to 4.1u with preloader .29 and bootmii as an ios installed and everything works like it should except for the new sd card menu at the bottom left corner. Once the system starts readind the card contents, it freezes and I have to power down by holding the power button. I did everything following zyxzero's guide (awesome guide btw) and that's the only problem I got. Any help would be greatly appreciated.
